P32 Uptake by Nuclei
1. A method for isolating nuclei in quantity from mammalian tissues is described. 2. The rate of uptake of radioactive phosphorus by nuclei is found to be quite rapid. The phosphorus was shown not to be taken up by exchange. 3. Nuclei of tumors accumulate more radioactive phosphorus than normal liver nuclei. This was shown to be due to mitotic activity and not a form of metabolism peculiar to t...
متن کاملUptake of P32 in resting cells of Clostridium perfringens.
Previous studies on resting cell metabolism of microorganisms relating to p32 incorporation into the intact cell have been carried out by Hotchkiss (1956) for micrococci, lactobacilli, and streptococci, and by Juni et al. (1948) for yeast. These studies in the main were concerned with turnover of various intracellular phosphoruscontaining compounds during conditions under which the organism was...
متن کاملIn Vitro Studies of P32 Uptake in Mouse Liver Mitochondria
Isolated mouse liver mitochondria were incubated in two types of P(32)-labelled sucrose-phosphate buffers. The first contained no added ATP or oxidizable substrate. The second contained added ATP. Samples were taken at specified times, up to 60 minutes, and analyses were made of the mitochondrial TCA-soluble inorganic P(32) and the total mitochondrial residue P(31) and P(32). The results of the...
متن کاملUptake of P32-labelled cyclophosphamide from arthritic knee joints.
The action of cytotoxic drugs such as alkylating agents and antimetabolites on active cell division and on the immune response has led to attempts to measure their efficacy as anti-inflammatory and antiproliferative agents in rheumatoid disease. In the chronic joint lesions of this condition there is proliferation of the synovial membrane with dense infiltration with lymphoid and mononuclear ce...
متن کاملUptake of Glycine-n 16 by Components of Cell Nuclei
An indication of the relative metabolic activities of various components of the cell nucleus is given by the rates at which they take up the nitrogen of glycine labelled with N 16. The nudear components which we have examined in the work here reported are desoxyribonudeic acid (DNA) and two protein fractions, histone and residual protein. Nuclear components of two kinds of cells have been studi...
